they are 2 entirely different design criterias being exhibited here.
the canon has opted for a rangefinder type camera with a flip out monitor and 4MP sensor
minolta has chosen to emulate a SLR type design with a 5MP sensor.

if your not going beyond 8x10 i doubt you'll see the difference in images. if you are going higher more is better.

i myself prefer the lens on the minolta (28-200) and the slr type of EVF/TTL viewpoint. i don't use the monitor to frame i use the EVF. i only use the monitor to review.

i just feel that the g3 is too limiting in too many places. but then again that is me and my wants and needs.
